摘　　要：由2-(1,2-亚乙二硫)亚甲基-3-羰基-5-芳基-4-戊烯酸与三苯基氢氧化锡反应,合成了九个标题化合物3.用X射线衍射法测定了3b的晶体结构.该晶体属三斜晶系,空间群Pl,α=0.9074(2)nm,b=1.6809(3)nm,c=2.1834(4)nm,α=77.57(3)°,β=88.04(3)°,γ=89.47(3)°,V=3.2503nm^3,Z=2;R=0.0592.由锡氧原子间距离可推测,该晶体中羧酸根作为双齿配体与锡原子形成了分子内五配位结构.Nine triphenyltin - 2 - (1,2- ethylenedithio) methylene - 3 - oxo - 5 - aryl - 4 - pentenicates were synthesized. The crystal structure of the title compound 3b (C33H28O3S2Sn) was determined by X - ray diffraction analysis . The crystal belongs to triclinic system , space group P 1 with a = 0.9074(2) nm , b =1.6809(3)nm, c =2.1834(4)nm, α=77.57(3)°, β=88.04(3)°, γ= 89.47(3)°, V=3.2503nm3, Z =2, R = 0.0592. In crystal of 3b, there exist intramolecular 0-Sn coordination bonds, with carboxylate group acting as a bidentate ligand: Sn(1)-O(1) = 0.2086(5) and Sn(1)-O(2) = 0.2594nm, having a deformed trigonal bipyramidal geometry.
